(A) If a MOU entered into pursuant to this subsection (c) would permit law enforcement officers to serve as armed school security officers at a school that is located within the jurisdictional boundaries of another law enforcement agency that is not the law enforcement officers' employing agency, then the MOU shall not take effect until approved in writing by the chief law enforcement officer of the law enforcement agency with law enforcement jurisdiction for the school.

(B) Notwithstanding title 6, chapter 54, part 3, or any other law to the contrary, a law enforcement officer who is serving as an armed school security officer pursuant to this section for a school located outside of the jurisdictional boundaries of the officer's employing agency shall, while acting within the scope of the officer's employment as an armed school security officer, have the jurisdiction and authority to enforce all laws of this state and of the county or municipality in which the school at which the officer is serving as an armed school security officer is located.

(d)

(1) The chief law enforcement officer of each law enforcement agency in this state shall prepare and distribute a list of its law enforcement officers who the chief law enforcement officer deems qualified and who are interested in serving as armed school security officers pursuant to this section to each LEA that is located within the law enforcement agency's jurisdictional boundaries and with which a MOU has been entered into in accordance with the provisions of this section. The chief law enforcement officer shall consider the federal Fair Labor Standards Act when considering an officer's qualification to serve as an armed school security officer.

(2) The chief law enforcement officer of a law enforcement agency may prohibit a law enforcement officer employed by another law enforcement agency from serving as an armed school security officer at a school located within the chief law enforcement officer's jurisdiction for reasons the chief law enforcement officer deems sufficient, including, but not limited to, if the law enforcement officer has received a disciplinary action within the last five (5) years that resulted in, at a minimum, a written reprimand. The chief law enforcement officer shall notify any such officer the chief prohibits from serving as an armed school security officer by sending a written notice of the prohibition to the law enforcement officer and the law enforcement officer's employing agency. The law enforcement officer is entitled to compensation pursuant to this section for any service as an armed school security officer performed by the officer prior to receipt of the written notice by the earlier of the law enforcement officer or the law enforcement officer's employing agency.

(e) If an LEA adopts a policy authorizing the use of armed school security officers, then funding for the armed school security officers may come from a law enforcement agency or from the LEA, including, but not limited to, local, state, or federal funds received by the LEA, for which purpose such funds may be lawfully expended.

An LEA shall not replace a school resource officer or other school security measure with an armed school security officer. A law enforcement agency shall not terminate a MOU for the provision of school resource officers based solely upon an LEA's adoption of a policy authorizing the use of armed school security officers.

(h) Following the conclusion of the 2020-2021 school year, the chief law enforcement officer of each law enforcement agency with law enforcement jurisdiction for a school that has utilized armed school security officers pursuant to this section shall submit a report to the governor, the chair of the education committee of the house of representatives, the chair of the education committee of the senate, and the commissioner of education on or before September 1, 2021, that details any school security deficiencies and that provides recommendations for security improvements for each such school. If the report requirement of this subsection (h) affects more than one (1) law enforcement agency within any one (1) county, then the affected chief law enforcement officers shall submit a single, consolidated report covering the schools that have utilized armed school security officers pursuant to this section.
